Binding of a molecule from a pathogen to a receptor initiates a signal transduction pathway. Which is the correct order of events in this pathway?

a. phosphorylation of NF-kB, binding of NF-kB to the promoter, activation of toll receptor, transcription of defense genes

b. binding of NF-kB to the promoter, phosphorylation of NF-kB, activation of toll receptor, transcription of defense genes

c. activation of toll receptor, phosphorylation of NF-kB, binding of NF-kB to the promoter, transcription of defense genes

d. activation of toll receptor, binding of NF-kB to the promotor, phosphorylation of NF-kB, transcription of defense genes

e. Binding of NF-kB to the promoter, activation of toll receptor, transcription of defense genes, phosphorylation of NF-kB
